The 2U V4 Systems Engine is a 2-in/4-out configuration capable of powering up to eight al-4 elements with two channels at 1600 watts each for the low frequency and two channels at 550 watts each for the high frequency (pure, sine wave rating). The V4 also handles all system management including loudspeaker protection and system-optimized alignment of EQ, time and crossover functions.

The V4 also includes networking capabilities as standard, allowing easy access to each element and/or device on the network through SystemVUE software.

“We designed the al-4 to be easily scalable and extremely versatile, allowing it to open new applications for line array technology,” explains Ken Berger, VUE’s co-founder and CEO. “The al-4 functions more like full-scale line arrays. Vertical coverage is limited only by the number of elements and their configuration, rather than by the physical limitations found in many compact line array designs. With our al-4, scaling up is simply a matter of adding more elements.”

The al-4 is sold in standard “blocks” with a single V4 Systems Engine and eight al-4 Acoustic Elements comprising a single block. Multiple al-4 blocks can be combined to address larger applications.

For applications where extended low frequency is required, the al-4 is fully compatible with a variety of VUE subwoofers. Flexible rigging options allow flying, ground stacking, and pole mounting on stands or atop VUE subwoofers.
